Water pressures on an inclined surface of wall with seismic are explained as follows.
Parameters
1. Density (gw) - The density of water.
2. Depth of water (hw)
- The depth of water below water surface.
3. Wall inclination (q)
- The inclination angle of wall surface from vertical.
4. Horizontal seismic coefficient (kh) - The horizontal seismic coefficient relative to gravity
acceleration (g).
Hydrostatic water pressure
Pressure inclination = q
Horizontal component = Inclined pressures x cos q
Vertical component = Inclined pressures x sin q
Seismic water pressure
Seismic water pressure is calculated based on Westergaard's equation as follows.
